DonutSMP Creeper Spawner Calculator
Estimate gunpowder per minute, hour and day for any spawner count - with DonutSMP's diminishing returns built in.
Creeper spawners produce gunpowder - the ingredient behind TNT and firework rockets, which makes it one of the most consistently consumed drops on DonutSMP. Every elytra flight burns rockets, and rockets burn gunpowder.
Enter your creeper spawner count below to estimate gunpowder per minute, per hour, and per day. The estimate uses the diminishing-returns curve measured on DonutSMP skeleton spawners (credit: 3706) applied as an approximation - the stacking throttle is server-wide, but creeper drop yields were not separately measured.

Full gunpowder price historyHow to use the creeper spawner calculator
- Enter your spawner count. Type the number of creeper spawners in your farm into the calculator - from a single spawner up to a full warehouse.
- Read the production estimate. The calculator applies DonutSMP's diminishing-returns spawner curve and shows the estimated gunpowder per minute, per hour, and per day.
- Check the income estimate. When recent gunpowder price data is available, the calculator also multiplies production by the latest average auction price to estimate income per hour and per day.
About the production curve
The formula behind this calculator was fitted by DonutSMP community member 3706 from real measurements of skeleton spawners: bones collected per minute across a range of spawner counts. It captures DonutSMP's diminishing returns - each additional spawner adds less than the one before it. DonutSMP applies the same stacking throttle to every spawner type, so this page applies the same curve to creeper spawners as an approximation - per-mob drop yields were not separately measured, so treat the numbers as estimates.
What gunpowder are used for
Gunpowder crafts into firework rockets (burned constantly by elytra travel) and TNT (burned by miners and base builders), giving it one of the strongest consumption sinks of any spawner drop.
Frequently asked questions
How many gunpowder does a creeper spawner produce on DonutSMP?
Production does not scale linearly on DonutSMP: a handful of spawners each produce roughly two drops per minute, but the server throttles output as you stack more, so per-spawner yield keeps falling. Enter your exact spawner count in the calculator above - it applies the diminishing-returns curve community member 3706 measured on DonutSMP skeleton spawners, applied to creeper spawners as an approximation and shows estimated gunpowder per minute, hour, and day.
Do spawners have diminishing returns on DonutSMP?
Yes. The more spawners you run, the less each individual spawner produces. The curve used by this calculator was fitted from real measurements on DonutSMP (credit: 3706): per-spawner output starts near two drops per minute and decays toward roughly 0.064 drops per minute per spawner at very large counts. That is why doubling your spawners does not double your income.
How much money do creeper spawners make per hour on DonutSMP?
That depends on the current auction price of gunpowder. When recent price data is available, this page multiplies the estimated gunpowder per hour by the latest average gunpowder price recorded by our DonutSMP price tracker and shows the result next to the production numbers. Prices move constantly, so treat it as a snapshot and check the live gunpowder price page before you commit to a build.
Is gunpowder in demand on DonutSMP?
Gunpowder has a genuine consumption sink: firework rockets for elytra flight and TNT for mining are both used up permanently, so demand renews itself. That makes creeper spawners a popular farm choice. To judge profitability, estimate your hourly gunpowder output with the calculator above and compare it against the current gunpowder price on the live price page.
